Novel 2-cyanoacrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene derivatives as potent anticancer agents
Ethyl 2-acrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate as well as its correspondingbis-derivatives,5-10, with aliphatic linkers were synthesized, fully characterized, and tested as novel anticancer agents. The targeted compounds,5-10, were obtained by the Knoevenagel condensation reactions ofbis-o- or -p-aldehyde with a molar ratio of ethyl 2-(2-cyanoacetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate of2in the presence of piperidine in excellent yields (93-98%). The in vitro anticancer activities of the prepared compounds were evaluated against HepG2, MCF-7, HCT-116, and BJ1 cells. Compounds7and9emerged as the most promising compounds, with IC(50)values of 13.5 and 32.2 mu g/ml, respectively, against HepG2 cells, compared with the reference drug doxorubicin (IC50: 21.6 mu g/ml). Real-time reverse-transcription polymerase chain reaction was used to measure the changes in expression levels of the COL10A1 and COL11A1, ESR1, and ERBB2, or AXIN1 and CDKN2A genes within the treated cells, as genetic markers for colon, breast, or liver cancers, respectively. Treatment of the colon cancer cells with compounds5,9, and10, or breast and liver cancers cells with compounds7,8,9, and10downregulated the expression of the investigated tumor markers. The DNA damage values (depending on comet and DNA fragmentation assays) increased significantly upon treatment of colon cancer cells with compounds5,9, and10, and breast and liver cells with compounds8,9, and10. The structure-activity relationship suggested that the increase of the chain of the alkyl linker increases the anticancer activity and the compounds withbis-cyanoacrylamide moieties are more active than those with one cyanoacrylamide moiety.
